Appeal No. 95-2535
Application 07/987,127
from consideration in Paper No. 7, the Final Rejection. 2
Appealed claim 9 was amended by appellants in Paper No. 14,
filed on July 14, 1994. This amendment was entered, as
indicated in Paper #19. An additional amendment to claim 9
was proposed by appellants as an attachment to Paper No. 18, a
Reply Brief, received December 2, 1994. As indicated in Paper
No. 19, a letter from the examiner mailed December 15, 1994,
neither the Reply Brief nor the attached amendment has been
entered.
Claim 9, as amended on July 14, 1994, is illustrative of
the subject matter of the claims on appeal and reads as
follows:
9. A method of revamping a pre-existing urea production
plant having a first urea synthesis reactor in fluid
communication with an ammonia stripping section for separating
free ammonia and carbamate from an aqueous urea solution
discharged from said first reactor, said method comprising the
steps of:
a) providing, upstream of said ammonia stripping section,
a second urea synthesis reactor of the once-through type
having a higher efficiency yield than said first urea
2We note that a Divisional Application 08/458,123 was
filed on June 2, 1995, presenting claims to a urea plant.
This application issued on August 26, 1997, as U.S. Patent No.
5,660,801 with claims very similar to pending claims 15-18.
Upon further prosecution, we presume claims 15-18 will be
canceled from this application.
